Interview with Steve Marinkovich, VP of Secure
Trax Systems.
Wireless LANs for Small Business.
Q. What hardware and software does a company need
in order to use wireless technology?
A. As far as wireless is concerned, including wireless
hardware, the industry is split into two types of wireless communications:
Wireless communication from phone or phone-type devices , through telecom
carriers.
Wireless communications for computer networks, both LAN's and WAN's ,
private corporate hardware.
For wireless through Telco carriers, there are three types of technologies
in use - TDMA, CDMA, and GSM. They are not compatible. There are a couple of
data mode technologies in use also. These are Mobitex radio and CDPD, which
have limited coverage to certain major metropolitan areas only. The big Telco
companies like Cantel, Bell Mobility, Rogers ATT, BellSouth, etc., implement
all the hardware, software and billing systems, and customers purchase phones
or devices like RIM email pagers that operate on their wireless platforms.
Basically, customers sign up for service plans that work in the desired area
with a device that the particular carrier is offering. You can't just pick a
device and say I want to use so and so as a carrier.
The other wireless communication industry is for computer networks. This is
still very new and just starting to come into the mainstream. These systems
replace the traditional hub and RJ45 LAN cables running to computers and
servers that link all the machines to form a network. The goal is create
wireless networks in corporations and/or homes to do away with the wires. The
computers connected to these systems talk only to the computers on their own
networks, not through telephone carriers, unless you provide a modem and a
telephone jack, etc. to access the outside world. Since the system is based on
a wireless TCP/IP protocol referred to as 802.11b, the NIC (Network Interface
Card ) in every PC and Server must be replaced with a wireless NIC. These
NIC's talk to a piece of hardware called a wireless bridge. This piece
provides the pathway from the wireless LAN to a standard Ethernet based LAN,
with network cables.
Large companies such as 3COM, Lucent, Nortel, IBM, etc. have this year
started offering these systems. Generally you have to buy the NIC’s and
bridge (comes with monitoring and management software) from the same vendor.
The software is not yet cross-compatible.
Q. What are the associated costs?
A. Obviously for the first type of wireless service, the cost is the
cell phone, PDA, etc. plus the monthly airtime usage charges. For wireless
LAN's, the cost is about $600 per NIC, and $1700 for the bridge, which comes
with the software. That's it. So, for an office with ten people, the cost
would be approximately $7700.00 Cdn.
Q. Is there technical support after wireless has been
implemented?
A. Sure there is support. All the large vendors that offer these
solutions give free support for a limited time (usually until the warranty
expires). After that there may be a per incident or annual service fee for
support.
Q. How long does it take for a business to implement a wireless
LAN?
A. For a business to become wireless, the business must buy the
components and then arrange for a systems integrator to set up the system.
These people usually charge $60 - $100 per hour, and will probably take 3 to 4
hours, provided there are no unexpected problems.
Q. To what extent is wireless being implemented?
A. Wireless LAN's are just starting to be implemented this year. I'd
say the current adoption rate is negligible compared to the installed base of
corporate networks. Network administrators want to test a technology for a
while first. Also, the price of the NIC cards will have to drop to the $200
level, in my opinion, before there is widespread deployment. In addition to
providing the benefit of going wireless, it must be hassle free, and it must
be affordable. Imagine what the cost would be for a company of 110,000 PC
users to install wireless at $600 a pop.
Q. What are some of the complaints?
A. The complaints in the past had been that the speed wasn't there as
claimed. The newer systems work much better. There are two big web sites with
reviews on wireless LAN systems, at
www.cnet.com and www.zdnet.com.
Go to the hardware - reviews sections.
Q. Which Operating Systems are used?
A. Currently Windows OS's are used: Win 98, Win NT, Win 2000.
They'll probably come out for systems for Mac soon. Wireless has been designed
primarily for corporate offices, which is why they started with Windows, and
not Unix systems.
